Differential transmitter and auto-adjustment method of data strobe thereof

An auto-adjustment method of data strobe for a differential transmitter, comprising:

• defining a plurality of detecting timings within a cycle of a clock signal;
• defining a first period and a second period within the cycle;
• respectively latching a data signal corresponding to the detecting timings for obtaining a plurality of strobe data;
• judging whether a transition of the data signal occurs within the first period or the second period by checking the strobe data, so as to obtain a detection result;
• and
• determining whether to latch the data signal at a rising edge of the clock signal or to latch the data signal at a falling edge of the clock signal according to the detection result.

An auto-adjustment method of data strobe for a differential transmitter, comprising:

• detecting a phase relation between a clock signal and a data signal and outputting a detecting result;
• determining whether to latch the data signal at a rising edge of the clock signal or to latch the data signal at a falling edge of the clock signal according to the detection result, so as to generate a latching result;
• and
• converting the latching unit to a differential output signal.
